Using Visual Basic

Create an application that displays a monthly payment on a loan. The application should also display the amount applied to the loan's principal each month and the amount that represents interest. Use the following names for the solution and project, respectively: Loan Solution and Loan Project. Save the solution in the VbReloaded2015\Chap07 folder. Change the form file's name to Main Form.vb. The application should use annual interest rates from 2% through 10% in increments of 1%, and use terms from 1 through 30 years. You can use the Financial. PPmt method to calculate the portion of the payment applied to the principal each month. The method's syntax is Financial.PPmt (Rate, Per, NPer, PV). In the syntax, Rate is the interest rate, NPer is the number of payment periods, and PV is the present value of the loan. The Per argument is the payment period for which you want to calculate the portion applied to the principal. The per argument must be a number from 1 through NPer. The method returns the calculated value as a Double number. You can either create your own interface or create one shown in Figure 7-44; the figure shows a sample run of the application. The combo box that gets the interest rate is the DropDown style. The combo ox that gets the term is the DropDownList style. The text box that displays the output has its Multiline and ReadOnly properties set to True and its ScrollBars property set to Vertical.
